Internal Medicine

Flesh-eating bacteria (necrotizing fasciitis) can enter the body through cuts, scrapes, or wounds and cause life-threatening infection. To lower your risk:

Avoid contaminated water: Stay out of oceans, lakes, hot tubs, or floodwaters if you have open wounds.
Cover wounds: Use waterproof bandages over cuts, scrapes, or recent surgical sites.
Practice good hygiene: Wash wounds thoroughly with soap and clean water, and clean them daily until healed.
Watch for warning signs: Redness, severe pain, swelling, fever, or skin changes near a wound need urgent medical attention.

If you're worried about a wound, unusual pain, or symptoms that seem to be getting worse quickly, don't wait to find out what's going on. Early recognition of a serious infection can save your life — and even non-emergency symptoms deserve clarity. Take a free, instant, online symptom check to better understand your symptoms and figure out your best next steps.

Good Hygiene: Keep any wounds clean and covered. Wash them with soap and water regularly.
